METHOD FOR INTRODUCING IMPURITIES

摘要

A method for introducing impurities comprising a step for forming an amorphous layer on the surface of a semiconductor substrate, and a step for forming a shallow impurity introduction layer on the semiconductor substrate rendered amorphous characterized in that the step for forming the amorphous layer is a step for irradiating the surface of the semiconductor substrate with plasma, and the step for forming a shallow impurity introduction layer is a step for introducing impurities into the surface rendered amorphous.
